TED-ED: What causes body odor? - Mel Rosenberg

Body odor is a complex phenomenon influenced by genetics, age, diet, and hygiene. It primarily results from the interaction between sweat secretions and bacteria on the skin. Eccrine glands secrete water and salt, while apocrine glands produce proteins and fats, which bacteria convert into odorous compounds. Factors like genetics, diet, and stress can affect body odor intensity. While washing helps, deodorants and antiperspirants are more effective in managing odor. Scientists are exploring the potential social and communicative roles of body odor.
